The spectrum of radiation given off by a black body can be described as continuous and emission. A continuous spectrum is produced by a source that emits radiation over a wide range of wavelengths, while an emission spectrum is produced by a gas that emits radiation at specific wavelengths. Black bodies emit radiation over a wide range of wavelengths, so a continuous spectrum is appropriate. Additionally, as the black body heats up, it emits more and more radiation at specific wavelengths, creating an emission spectrum. Therefore, both continuous and emission spectra are appropriate to describe the spectrum of radiation given off by a black body.
